MACHINE FOR CLOSING THh CHANNELS lN BOOT AND SHOE SOLES.

SPECIFICATION forming part of Letters Patent No. 268,741, dated December5, 1882. Application filed September 13, 1882. (No model.)

To all whom it may concern: I

Be it known that I, DANIEL S. SMITH, acitizen of the United States,residing at Rockland, inthe county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Machines forClosing the Ohannels ofBoots and Shoes, of which the following is aspecification.

This invention relates to improvements in machines designed for closingthe channels in the soles of boots and shoes; and the inventionconsistsina novel construction and combination of devices, which will befully hereinafter described, and pointed out in the claims, theobjectbeing to provide simple and efficient means whereby the lip may begradually and rapidly closed into the channel and the sole afterwardsmoothed.

The invention is illustrated in the accompanying drawings, in whichFigure 1 represents a sectional side view. Fig. 2 is a transversesection in the plane (0 00, Fig. 1, on a larger scale than the previousfigure. Fig. 3 is a similar section in the plane :1 3 Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A. designates a bifurcated support, the armsa a of which form the-bearings for a spindle, B. On this spindle,between thearms a a, are mounted two pulleys, G 0, one fast and theother loose, so that by placing a driving-belt upon the fast pulley arapid revolving motion can be imparted to the spindle, and by moving thebelt from the fast to the loose pulley the motion of the spindle canbestopped. On one end of the spindle B is firmly mounted a head, D, thesurface of which is convex in the direction of its axis and providedwith a series of spiral ridges, b I), each of which extends in a uniformpath in the direction of thelength of the head, and continuously fromend to end thereof.

In order to close the channel of a sole, 1 hold the same up against thesurface of the head D,

and as this head revolves its spiral ridges act upon the lip of thechannel and turn the same down gradually, so as to close the channelwith great rapidity. This operation is facilitated by the convex shapeof the surface of the head; t the operation may also be accomplished ifthe head is made in the form of a cylinder with the spiral ridges.

I am aware that a machine has been constructed for this purpose whichconsists of a head containing a series of pivoted rubbers. In thismachine the working-edges of the rubbers run parallel to the axis of thehead, and before they can be brought to act upon the lip of the channelthis lip must be at least partially turned down over the channel;otherwise said rubbers would be liable to turn the lip of the channeloutward instead of inward over the channel. This difliculty is avoidedin my machine, since the ridges b b, on account of their spiral form,act upon the lip of the channel so as to close the same gradually; andthey are not liable to turn the lip in the wrong direction, provided thesole is held up against the head in the proper manner. On the oppositeeud of the spindle B, I have shown a head, E, which may be used tosmooth the surface of the sole after the lip has been closed. This headconsists of two flanged disks, 0 0, between which is situated a packing,d, ot'india-rubber, and a series of metallic anti-friction rollers, c,Fig. 3, which rest upon the rubber cushion (Z, and are held in place bytheflanges of the disks 0. One of the rollers, 6*, Fig. 1, enters intosockets formed for this purpose in the disks 0, so that it can freelyrevolve round its own axis, but not roll on the rubber cushion. Thisroller prevents also the rolling motion of the remaining rollers,leaving them free, however, to turn on their own axis.

I am aware that a wheel for shaping the edges of boot-heels has beenarranged on a vertical shaft to revolve in a horizontal or inclinedplane, the surface of the wheel. being convex and provided with teeth orserrations; but such a device could not be practically used for thepurposes of my invention, as the teeth on the wheel would rasp the lipof the channel, and by casting into the same prevent the lip from beinguniformly and gradually closed down over the channel in a perfectlysmooth.

and unbroken condition.

I am further aware that a burnisher-head has been composed of a hollowconical body, which is formed into annular steps of varying diameter,the surface of each step being convex and formed withburnishing-surfaces composed of grooves or corrugations of differentwidths and sizes; but the construction ofsuch ahead would 5 renderitunfit for the purposes ofmy invention,

owing to the inconvenience, if not impossibility, of presenting the soleproperly to it to produce the uniform, gradual, and rapid turning of thelip over the channel. Besides, the

to grooves or corrugations composing the burnishing-surfaces would notefficiently perform the functions attained by my uniform and continuousspiral ridges, for the reason that they would tend to upset or batterthe lip, catch 15 p and tear the same, and prevent the lip from beinguniformly turned over the channel in a perfectly smooth condition, whichI accomplish by my invention.

What I claim as new, and desire to secure by 20 Letters Patent, is"

1. A sole-channel closing and smoothing apparatus consisting of ahorizontal shaft arranged to revolve in a supporting-frame, and providedwith the head D, having the series of spiral ridges b, for closing thechannel of the 25 sole, and with a head, E, composed of a cush- MATTHEWDOLAN, H.
